Abstract

The new ligand, hydrotris[3-(diphenylmethyl)pyrazol-1-yl]borate, Tp(CHPh2), has been synthesized and its coordination chemistry was compared with that of the analogous Tp(iPr). The new ligand was converted to a variety of complexes, such as M[Tp(CHPh2)]X (M = Co, Ni, Zn; X = Cl, NCO, NCS), Pd[Tp(CHPh2)][eta3-methallyl], CoTp(CHPh2), and Co[Tp(CHPh2)](scorpionate ligand). Compounds Tl[Tp(CHPh2)], 1, Co[Tp(CHPh2)]Cl, 2, CoTp(CHPh2)(DMF), 3, NiTp(CHPh2)(DMF)2, 4, CoTp(CHPh2), 5, Co[Tp(CHPh2)][Ph2Bp], 6, Co[Tp(CHPh2)][Bp(Ph)], 7, Co[Tp(CHPh2)][Tp], 8, and (Ni[Tp(CHPh2)])2C2O42, 9, were structurally characterized.

摘要

新型配体三[3-(二苯甲基)吡唑-1-基]硼酸酯（Tp(CHPh2)）已合成，并将其配位化学与类似的Tp(iPr)进行了比较。该新型配体被转化为多种配合物，如M[Tp(CHPh2)]X（M = Co、Ni、Zn；X = Cl、NCO、NCS）、Pd[Tp(CHPh2)][η3-甲基烯丙基]、CoTp(CHPh2)以及CoTp(CHPh2)。化合物Tl[Tp(CHPh2)]（1）、Co[Tp(CHPh2)]Cl（2）、CoTp(CHPh2)(DMF)（3）、NiTp(CHPh2)(DMF)2（4）、CoTp(CHPh2)（5）、Co[Tp(CHPh2)][Ph2Bp]（6）、Co[Tp(CHPh2)][Bp(Ph)]（7）、Co[Tp(CHPh2)][Tp]（8）以及(Ni[Tp(CHPh2)])2C2O42（9）的结构已得到表征。
